摘　　要：在实验室条件下,研究了铝电解质分子比、电解温度、电解时间、电流密度等因素对铝电解质和金属钠对阴极炭块渗透与侵蚀的影响。由试验得出了一些减轻电解质和金属钠对炭阴极的渗透与侵蚀,从而延长电解槽寿命的措施。The effect of bath ratio,temperature and time of electrolysis,current density on permeation and corrosion of bath and sodium to cathode block were studied in laboratory.The paper gave the ways how to reduce the permeation and corrosion of bath and sodium to cathode block through laboratory test.The ways will extend the life of aluminium cell.
